    ABSTRACT: This paper presents a single-stage isolated power factor corrected power supply (SSIPP) fed permanent magnet brushless DC (BLDC) motor drive. An advantage of fast voltage regulation with single voltage control loop of SSIPP is utilised to develop a power factor correction (PFC) based BLDC motor drive. The speed of BLDC motor is controlled by varying the DC link voltage of the voltage source inverter (VSI) feeding BLDC motor using a single voltage sensor. A boost-flyback SSIPP operating in discontinuous inductor current mode (DICM) is used for the voltage control with improved power quality at AC mains. A fundamental frequency switching of VSI is used instead of pulse width modulation (PWM) switching to avoid high frequency switching losses in it. The performance of the proposed BLDC motor drive is evaluated for wide range of speed control with power quality indices with-in the recommended limits of international power quality standards such as IEC 61000-3-2.

    ABSTRACT: The paper discusses the problem of speed and rotor position estimation for the Permanent Magnet Synchronous Motor (PMSM) and presents a family of estimation methods. Estimation is done sequentially: first, the EMFs are obtained using a sliding mode observer; then, the speed is estimated. The estimators are based on the model of the PMSM in the stationary reference frame. The paper presents an SM observer for the EMFs (the front observer) and various observers for the speed (the back observers). It is shown that the speed estimation process offers many mathematical options - it can be adaptive, sliding-mode based, algebraic, or it can use a doublemanifold sliding mode structure. The properties of the various speed observers and their feasibility and accuracy are discussed. The method can be applied in a sensorless PMSM drive where the speed and rotor position angle are needed for control implementation. The paper presents the design of the observers along with simulation results and experimental tests.

    ABSTRACT: In the present scenario, the development of multilevel inverter is becoming popular for industrial applications and higher scale renewable green power technologies such as fuel cell, PV cell and wind turbine systems connected to the load. But the traditional multilevel topologies have large components and complex Pulse Width Modulation (PWM) controller leading to reduced harmonics and voltage stress on the load. Therefore, a new topology of a cascaded multilevel inverter employing less number of switches with reduced gate driver circuits and simple control scheme is presented in this paper. A comprehensive MATLAB/Simulink model of a seven-level inverter and the generation of control pulses using multi-carrier-based PWM is evolved and discussed. With the aid of LabVIEW, an experimental prototype is developed and their results are compared with simulation results.

    ABSTRACT: In this research study, direct torque and flux control of an Induction Motor Drive (IMD) using Sliding-Mode Speed Controllers (SMSC) and Fuzzy-Logic Speed Controller (FLSC) are presented to achieve high performance of stator current, electromagnetic torque and motor speed in both transient as well as in steady-state conditions. The PI Speed Controller (PISC) gives good steady-state performance, but poor dynamic response. Therefore, the SMSC is considered to achieve continuous control of motor speed and also electromagnetic torque. Furthermore, FLSC is considered to get high performance, dynamic tracking and speed accuracy at various load torque conditions. The performances of each speed controller techniques are tested under various load toque and speed condition for its robustness. A detailed comparison of different control approaches are carried out in a MATALB/Simulink environment at different operating conditions, such as forward and reversal motoring with no-load, load, sudden change in speed and sudden zero speed.

    ABSTRACT: This paper deals with a three-level Neutral Point Clamped (NPC) rectifier-based midpoint converter-fed Switched Reluctance Motor (SRM) drive. The three-level NPC rectifier for midpoint converter-fed SRM drive is used for improving power quality at AC mains and to balance the DC link capacitor voltages. The proposed three-level NPC rectifier is designed, modelled and its performance simulated using MATLAB/Simulink environment. The performance of proposed three-level NPC rectifier-based midpoint converter-fed SRM drive is compared with a six-pulse bridge converter-fed SRM drive to demonstrate its improved power quality.

    ABSTRACT: This paper presents a STATCOM-based voltage and frequency regulation for stand-alone asynchronous generator feeding linear and nonlinear loads. The SEIG have inherent poor voltage and frequency regulation. The voltage and frequency depend upon the load current and power factor of the load with fixed excitation capacitor employing unregulated turbines. The changing consumer load requires variable reactive power compensation for excitation requirement. Consumer load contains harmonics and performance of SEIG is largely affected by these load harmonics. A current controlled voltage source inverter working as STATCOM is used for harmonic elimination, load balancing and variable reactive power compensation. A DC chopper with dump load is connected across DC bus capacitor to regulate varying consumer load. The control algorithm has been first co-simulated with processor in the loop (PIL) and then experimentally validated. The transient behaviour of developed prototype system for application and removal of balanced, unbalanced, nonlinear load is investigated.

    ABSTRACT: In this paper, the nonlinear phenomenon in DC/DC buck converter is studied. A practical design for a DC/DC buck converter was considered in this study, which results in a more comprehensive understanding for the phenomenon. The nonlinearity of the buck converter is studied using the iteration mapping technique. The results showed that if the system has a well-designed buck converter as well as a feedback controller, then it does not exhibit any nonlinear behaviour. To verify these results, a buck converter, with non-practical parameters, was also studied. In this case, the results showed bifurcation and then chaotic behaviour for the output voltage and inductor current as the input voltage changes. A comparison between the two cases is discussed in more details.

    ABSTRACT: Power electronics equipment is deployed for control of power flow in electrical domain. Steady and fast growth in controller, active and passive power and control components, power control topologies etc. and the impact on overall gains it makes to society have led the evolution process of power electronics field to mature fast. Apparently, contemporary SMC concepts with their simple implementation procedures using structure switching mechanism along with their ability to reject disturbances and also generate parametric insensitivity remain very attractive research area for several decades. However, compared to PI control, their market penetration in power electronics domain is below expected line. Inertia to market penetration of SMC idea is large. For practical implementation, PI control remains as industry standard. This paper, using experimental design approach, tries to figure out basic differences between PI control and SMC concepts in shaping up a completely engineered product in power electronics domain.

    ABSTRACT: The switched-mode power supplies are widely used in very low voltage and high-power applications where large conversion ratios are required. In such cases, the quadratic buck converter is the suitable one compared to buck, cascaded buck and multi-phase choppers, because of their limitations in switching frequency and losses. This paper presents mathematical analysis, design and simulation of a quadratic buck converter using fixed frequency Pulse-Width Modulation (PWM)-based Sliding-Mode (SM) controller in order to obtain fast dynamic performance. The design aspects include choice of sliding surface, deriving existing and stability conditions, control parameter selection and their analysis. The performance of the proposed converter is compared with the conventional Average Current-Mode (ACM) controller. In average current mode, the tuning of the PI controller for the inner current loop and outer voltage loop is done using bode plots. The simulation results for the two types of controllers are represented for analysing dynamic performance, as well as line and load regulations.

    ABSTRACT: A number of techniques have been developed for estimation of speed or rotor position in motor drives. In this paper, an extended Kalman filter (EKF) is developed for the estimation of speed and rotor position using only the measurements of three phase stator currents. Conventional mechanical sensors are not needed for this estimation. The paper proposes the modelling of the dynamic equations of the permanent magnet synchronous motor (PMSM) to describe the dynamics in terms of direct axis current and voltage, quadarture axis current and voltage, rotor position and synchronous speed. Unlike the earlier papers in this direction, the present work does not take any input like vd or vq into the Kalman filter, but uses only the sensed line currents as measurements. The performance evaluation of the extended Kalman filter with online estimation of the speed and rotor position of a PMSM is presented with simulation results, for a varying load torque.

    ABSTRACT: A new digitally controlled, bridgeless AC/DC buck converter that operates in discontinuous-input-voltage mode (DIVM) is presented. It inherits power factor correction property and draws continuous input current during conduction period. In addition, the efficiency of the proposed buck PFC rectifier is improved by adopting a bridgeless configuration. The converter also works as a voltage-doubler which reduces the size of the output capacitors. Detailed operating analysis, design criteria, and modelling of the buck converter are reported. Experimental results for verifying the theoretical analysis are also presented.
